"Gotama has not eliminated the forces of Mara but became immune to them.

When regarded with mindful awareness, greed and hatred are seen for what they are: impermanent emotions that, when left to their own devices, will fizzle out. Realizing that they are conditioned processes and not essentially 'me' or 'mine' takes away their power.

Nirvanic freedom is the result of understanding how reactivity works.

Mara is whatever imposes constraints and limits upon us."
